Abstract

Develop the understanding and clinical reasoning skills you’ll need to confidently manage dysphagia in professional practice! This logically organized, evidence-based resource reflects the latest advancements in dysphagia in an approachable, student-friendly manner to help you master the clinical evaluation and diagnostic decision-making processes. Realistic case scenarios, detailed review questions, and up-to-date coverage of current testing procedures and issues in pediatric development prepare you for the conditions you’ll face in the clinical setting and provide an unparalleled foundation for professional success.

  • Comprehensive coverage addresses the full spectrum of dysphagia to strengthen your clinical evaluation and diagnostic decision-making skills.
  • Logical, user-friendly organization incorporates chapter outlines, learning objectives, case histories, and chapter summaries to reinforce understanding and create a more efficient learning experience.
  • Clinically relevant case examples and critical thinking questions throughout the text help you prepare for the clinical setting and strengthen your decision-making skills.
  • Companion Evolve Resources website clarifies key diagnostic procedures with detailed video clips.

Parkinson’s Disease. Although dysphagia secondary to Parkinson’s disease appears to be common, accurate measurements are restricted by subject selection bias and dysphagia detection methods. However, most authors agree that dysphagia occurs in at least 50% of patients with Parkinson’s disease.32-34 In 72 patients with Parkinson’s disease of varying severity, Leopold and Kagel35 found that as many as 82% reported swallowing difficulty. The prevalence of dysphagia may be higher in patients with Parkinson’s disease who also have significant dementia.36 6
